Fan Tray

The device provides a Fan Tray module, located on the front panel, which is concealed by a fan tray cover. The Fan Tray module contains six individual fans which cool the device's internal components to maintain an acceptable operating temperature inside the chassis.

The Fan Tray module draws air in from the outside through the perforated fan tray cover on the front panel (see following figure). A replaceable air filter, located inside the fan tray cover, removes dust particles from the sucked in air. The incoming air passes through the chassis, cooling the internal components and then exits the chassis through the vents on the rear panel (see following figure).

Airflow Directions through Chassis

When installing the chassis, make sure there is sufficient front- and rear-side clearance for proper airflow into and out of the chassis.

Fan Tray Cover

The Fan Tray provides a LED indicating the operating status of the Fan Tray module. For more information, see FAN LED.

During system operation, the inner ambient temperature is continuously monitored. Upon excessive temperature conditions, an SNMP Temperature Alarm is generated (acBoardTemperatureAlarm). Upon a speed degradation or full stop of any fan, an SNMP Fan Alarm (acFanTrayAlarm) is generated.

The Fan Tray module is hot-swappable, allowing you to replace it even when the device is powered on. The Fan Tray module, fan tray cover, and air filter are available as field-replaceable units (FRU). For replacing the Fan Tray module, see Replacing the Fan Tray Module. For replacing the air filter, see Replacing the Air Filter.

For replacing the Fan Tray module or any of its components, perform only the instructions as described in Replacing the Fan Tray Module.
